A new array was suggested for effective leakage detection of concrete water facility. This array was modified to serve the purpose. Plus and minus currents have been installed respectively on the upstream and downstream water in order to detect the flow of water floating through the crack of facility. Potential poles in two lines have been installed closer than current sources to the weir to measure potential difference in upstream and downstream. Interpreting the potential difference data acquired by the new array, we could predict that where is the leakage zone. The possibility that can distinguish the leakage zone has been confirmed by numerical and physical modeling and problem position expected to leak was verified in field exploration.
